[1] The Héraðsvötn is located in Skagafjörður, a municipality in northern Iceland, and it is one of the deadliest waterfalls in the country.

[2] Héraðsvötn is formed by the confluence of multiple rivers that come together at the lower part of the town of Tunguháls, where the eastern and western branches of Jökulsá meet.

In the middle of Blönduhlíð, Héraðsvötn splits into two forks that flow to the sea on either side of Hegranes.

They converge a little farther down where settlements begin in the two valleys that they flow into and was named Héraðsvötn on account of this.

Where the lake flows into the fjord, they are called the western and eastern estuary.This article related to a river in Iceland is a stub.
